Containers

These sterile PETG (polyethylene terephthalate glycol) Erlenmeyer flasks are used for mixing, containing, and storing solutions. PETG flasks are very clear and have easy to read graduation marks. These are shatterproof and are an ideal alternative to glass. Temperature range is -40 to 70° C (-40 to 158° F). (12 per PK )

Boiling, round bottom flasks with ground glass joints. Our boiling flasks are made from low-expansion borosilicate glass. Feature uniform wall thickness for superior mechanical strength and shock resistance. Ideal for boiling, heating and mixing in the la (24 per CS )

United Scientific™ Unisafe™ Narrow Mouth Vented Wash Bottle, LDPE, 500 mL (6 per PK )

Manufactured from 5.1 expansion borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class B requirements, these threaded culture tubes are suitable for a variety of lab settings. Each tube is heat-treated at temperatures exceeding 500° C and immediately packed in a shrink-wrapped cardboard tray, 250 tubes per tray. This process avoids contamination and increases the strength and durability of the glass. Dimensional tolerances are strictly controlled for a uniform shape, including rounded bottoms and polished tops with smooth edges. Each tube has a chevron-shaped white enamel marking spot. Threaded necks accept a phenolic screw cap, not included. Available in six sizes, from 8 mL to 33 mL. (1000 per PK )

United Scientific® Volumetric Flask, Class A, Individually Certified, Wide Mouth, 100 mL (1 per EA )

Our beakers are made from low-expansion borosilicate glass. Beakers feature heavy and uniform wall thickness, spouts designed for easy pouring, and beaded tops. The 20ml and larger sizes also have a double graduated metric scale and a marking area. Tolera (12 per PK )

Pack of 12 heavy-duty beakers with 50ml capacity. Made from low-expansion borosilicate glass with extra-thick walls, these beakers are ideal for tough handling conditions, including mechanized washing. Also include white printed graduations (from 10-40ml, at 10ml intervals) and a marking area. Tolerance for beakers is approximately +/- 5%. (12 per PK )

United Scientific™ Narrow Mouth, HDPE, reagent bottles are manufactured from USP Class VI resin that is FDA-21CFR compliant. The amber bottles are designed to reduce UV light transmission to protect light-sensitive contents, and conform to USP requirements for storage of light sensitive materials. Excellent chemical resistance to most acids, bases, and alcohols. Polypropylene caps are included. (72 per PK )

UniSafe™ unitary LDPE wash bottles have a built-in delivery tube making it a one-piece bottle and reducing the risk of contamination since there are less assembly parts. The unitary wash bottles are easy to squeeze and dispense a steady stream. (6 per PK )

Pre-cleaned borosilicate glass test tubes without rims. Tubes can be used for hot or cold applications, are reusable, and can be autoclaved. (72 per PK )

Borosilicate glass flasks are designed to give the best combinations of thermal shock resistance and physical strength. Feature heavy-duty rims and graduations in durable white enamel. (8 per CS )

Flat-bottom boiling flask with 1000ml capacity. Made from low-expansion borosilicate glass, this flask features uniform wall thickness for superior mechanical strength and shock resistance. (1 per EA )

Narrow Mouth Polypropylene bottles are rigid, translucent, have excellent contact clarity, and can be autoclaved. (6 per PK )

Dropping Bottle, Assembled, LDPE, 60ml (12 per PK )

Our polypropylene conical measuring cylinders are ideal for measuring small quantities of reagents. They are autoclavable and have excellent contact clarity. The hexagonal base provides excellent stability to the cylinder, and the tapered spout enables easy pouring of reagents. Features easy-to-read raised graduations. (12 per PK )

Double metric scale, calibrated to contain. Borosilicate glass cylinders with pour spouts feature heavy uniform wall tubing and plastic hexagonal bases. All cylinders come with bumper guards. (1 per EA )

This heavy duty autoclavable bottle features thick walls and is designed for repeat vacuum applications. Cap includes a non-toxic silicone O-Ring for a secure seal. Threads should be completely disengaged before autoclaving (1 per EA)

Polypropylene beakers with pouring spouts are ideal for general laboratory use.  Includes rectangular handle for easy carrying and pouring.  All sizes have easy to read silk-screened graduations.  Autoclavable. (6 per PK )

Tall form crucibles include lids. Crucibles are glazed on inner and outer, surfaces except for the outside bottom and rim. (6 per PK )

Designed for repeated laboratory use, United Scientific™ CrystalClear™ crystallizing dishes are made from industrial grade borosilicate 3.3 glass. Dishes are autoclavable, with excellent chemical resistance, a low temperature gradient, and can withstand high temperatures and thermal shocks. (6 per PK )

Clear quartz glass crucibles are useful for analytical applications that require ashing of samples. Can withstand a continuous operating temperature of 1050°C. Lids, also manufactured from quartz, are sold separately. (1 per EA)

Round form evaporating dishes include lip. Glazed inside and outside on both sides, except for large dishes (greater than 385 ml) which are glazed inside and partially outside. (1 per EA)
